Thanks - John After unification identical binaries in different vservers are hardlinks to the same inode. Therefore they are the same file / binary from a kernel perspective and can reuse cache and memory. If your memory usage will be lower with unification depends on if all the running binaries are unified or not. Regards, Christoph
